MOUNTING MACHINE.

Application filed March 14, 1925. Serial 110. 15,524.

This invention relates to an apparatus for mounting paper upon pasteboard, or the like. I I

In the type of mounting machine which I isat present in use, and which is illustrated in my prior Patent 1,477,032, dated December 11, 1923, the board is fed in a rectilineal path between two cooperating mounting rolls, which presentothe sheets which are to be mounted on the board to the latter and mount the sheets upon the board as it passes between the rolls.

In this machine, when the board reaches a predetermined point in its travel, prior to its passage between the mounting rolls, it is arrested in its movement, so that when the board reaches the mounting rolls the sheets which are to be mounted on the board will be properly positioned and aligned with the latter.

The present invention relates particularly to the mechanism for stopping the board in its movement toward the mounting rolls, and for feeding the board positively to the rolls, so that the proper alignment will be obtained.

In the drawings I have illustrated two forms of the invention, in which Figure 1 is aside elevation of one of the forms; and

Figure 2 is a similar view of the other form.

In Figure 1 of the drawings the mount ing rolls 5 and 6 are mounted in suitable bearings 7 and 8. In order that the board 9 may be positively fed to the mounting rolls 5 and 6, at predetermined times, I have provideda pair of standards 10 (one only being shown in the drawings), which are mounted on the frame 11 of the machine. A feed roll 12 is mounted in bearings in these standards 10, and is actuated by a shaft 12, which is geared thereto at 13 and which is itself actuated by cooperating gears 14, one of the gears being upon the shaft 12 and the other upon a shaft 15. Thissha'tt 15 receives its motion from the interengagement of the worm 16 with a worm wheel 17, which latter is actuated by the mounting roll 6. Thus it will be seen that the actuation of the feed roll 12 is dependent upon the movement of the mounting roll 6.

A roll or disk 18 is mounted in bearing boxes 19, which. are adapted to move vertically within races 20. These bearing mounting rolls 5 and 6.

the board.

boxes, and consequently the roll or disk 18,

are urged downwardly sothat the latter wlll be normally urged toward the feed roll 12 by resilient means such as springs 21, the tenslon of which may be regulated by means of an abutment and adjusting screw 22. Thus the cooperation of the roll 12 with the roll ,or disk 18, and the actuation of the former roll, will feed the board 9 toward the In order that the roll or disk 18 may be raised at predetermmedtimes so as to render the feeding actlon of the roll 12 ineffective to feed the board 9 to the rolls 5 and 6, I have provided each end 01 the roll 12 with a cam 23 with which cam a rod 24 slidably mounted for vertical movement in a guide 25 is adapted to cooperate. This rod is connected at 26 to a bearing box 19. Thus, when the roll 12 rotates the roll or disk 18 will be intermittently raised by the action of the cams, and lowered by the action of the spring 21;

In order that the boardmay be stopped] 111 its progress toward the mounting rolls 5 and 6, when the roll or disk-18 is raised, I have provided a stop finger 27, which is on a lever 28, and is adapted to be moved into the path of movement of the board at a point adjacent to the rolls 12 and 18. This lever 28 is pivoted at 29 on the frame 11, and is actuated so that the stop finger will be moved into and out of the path of move ment of the board by means of a cam 30 which is mounted on or actuated by one of the mounting rolls. 1

Because of the fact that the feed'roll 12, the cams 23, the mounting rolls 5 and 6, and the stop finger 27, are actuated from a common source, their action will be synchronized. Because of this synchronous actuation of these parts when the feed roll or disk 18 is raised to an inoperative position by the cooperation between the cams 23 and the rods 24, the stop 27 will be lowered into the path of movement of the advancing board, and, by engaging the leading edge of said board, will arrest the movement of Then, after the cams 23 complete their cycle, the rods 24 will be released, and the rolls or disks 18 will be lowered by the action of the springs 21, so that the feed rolls in cooperation will bring the board forward. Simultaneously the stop 27 will be moved out of the path of travel of the board, and. the board will move forward to the mounting rolls under the action of the feed rolls.

In the other form of invention illustrated in Figure 2, substantially the same arrangement is shown, except that the stop which is here designated by 27 is carried on each side of the machine by a lever 28, which is pivoted at 29', and which is connected at 30 with the adjacent bearing box 19; The action in this form is much the same as in the previously described form, the upper roll or disltlS being moved upwardly by the coaction between the rod 24 and the cam 23, and being moved downwardly by the springs 21. The stop 27, being actuated by levers 28, which are connected to the bearing boxes 19, moves in synchronism with the upper roll or disk 18. so that when the latter is moved into feeding relation with the lower roll 12 the stop is elevated and moved out of the path of travel of the board 9.

I have described particular embodiments of the invention, but it is to be understood that I do not wish to be limited to the details of these constructions, except as is necessitated by the claims.

What I claim is:

1. In a machine of the class described the combination with a pair of mounting rolls of cooperating teed rolls, a vertical guide- Way a bearing box movable in said guideway and supporting one of said teed rolls, meansactuated by the other of said feed rolls to move the bearing box in the guideway to separate the feed rolls,resilient means for returning the movable feed roll to its eooperating relation with the other feed rolh a stop element, and means for moving the stop element into the path of movement of the Work as the feed rolls are separated and out of the path ofmovement of the work as the feed rolls are brought together.

2. In a machine of the class described the combination. with a pair of mounting rolls of cooperating feed rolls, a vertical guideway, a bearing box movable in said guideway and supporting one of said feed rolls. means actuated by the other of said teed rolls to move the bearing box in the guideway to separate the feed rolls, resilient means for returning the movable feed roll to its cooperating relation with the other teed roll, a stop element, a lever supporting the same, and a cam on one of the mounting rolls adapted to actuate the lever to move the stop element into the path of movement of the work as the feed rolls are separated and out of the path of movement of the work as the feed rolls are brought together.

3. In a machine of the class described the combination with a pair of mounting rolls of a feed roll adapted to rotate on a fixed axis, a pair of vertical guideways. bearing boxes movably mounted in said guideways, a shaft extending between said bearing boxes, a feed roll mounted on said shatt, resilient means for urging the last mentioned feed roll toward the tirst mentioned teed roll, cams rigid with the first mentioned teed rolh rods cooperating with said cams and connected with the bearing boxes to move the feed roll carried thereby against the action oi the resilient means, and a stop element adapted to move into and out of the path of travel of the work in synehronism with the movement of the movable teed roll.

4. In a machine of the class described, a pair of mounting rolls, a pair of feed rolls, means for movabl v supporting one of said feed rolls means actuated by the other of said teed rolls to operate said supl'iorting means to separate the teed rolls. means tor returning the movable teed roll to its co operating relation with the other teed rollr a stop element, and a single lever adapted to move the stop element into and out of the path of travel of the work in svnchronism with the movement of the movable teed roll.

5. In a machine of the class described, a pair of feed rolls means tor biasing the il ced rolls to their cooperative position, a vertical guideway, a bearing box movable in said guideway and supporting one oi said teed rolls, and means actuated by the ether of said teed rolls to move the bearing box in the guideway to separate the teed rolls.
